Module: ADSL2-LINE-MIB

OID (symbolic): ADSL2-LINE-MIB::adsl2LConfProfScMaskUs

OID (numeric): 1.3.6.1.2.1.10.238.1.5.1.2.1.3

Node type: OBJECT-TYPE

Type: Adsl2ScMaskUs

Access: read-create

Description: Sub-carriers mask. A bitmap of 64 bits that allows masking up to 64 downstream sub-carriers, depending on NSCds. If bit i (0 <= i < NSCus) is set to '1', the respective upstream sub-carrier i is masked, and if set to '0', the respective sub-carrier is unmasked. Note that there

should always be unmasked sub-carriers (i.e., the object cannot be all 1's). Also note that if NSCus < 64, all bits i (NSCus < i <= 64) should be set to '1'.

What is adsl2LConfProfScMaskUs?

This OID stores a 64-bit bitmap that masks (disables) specific upstream sub-carriers in ADSL2. Engineers mask upstream sub-carriers to work around interference or line impairments on the upload path. For example, setting bit 20 to 1 disables upstream sub-carrier 20 to avoid a troublesome frequency band.
